The ST has Decided it likes Vaping, and I'm a very disappointed parent:

Everyone I ask is quick to jump to Turbo seals but the big thing is its super Intermittent like will go a week with no smoke then smoke for 20 seconds and gone.

Even in the Video, the smoke at the end is just condensation, also on this Turbo its, a Steel ring like a Piston ring and that doesn't seem likely to go like a normal gasket.

What guys have suggested to me is an issue with the 1-way valve on the Inlet oil feed going into the turbo. The coolant hasn't dropped any and engine oil doesn't have a trace of milkiness so at least it's not the head gasket. So from what I can gather its either the inlet or outlet from the Turbo oil and it's basically just dumping a bit right into the turbo and burning it out.

Also got a P2196 and P0140 both related to CAT Sensors, I've read this isn't so much a problem more so that I'm running a full 3" de-cat system with only rear boxes with no software and once I got software it'll sort Thoughts

Ended up been the Filter housing PVC pipe up to the Cam cover, I still had the plastic one and it fell to pieces, put on a temp hose and cars running like a dream, Ordered the Rubber OEM one to replace it. So heads up anyone with a Pre FL, maybe worth replacing yours now before it becomes brittle and cracks

Yeah learning that now, Was just a huge relief to know my turbo isn't buggered, Getting anything ST here in New Zealand is a real mission, but I do love the car
